Option 2:

No shot Antonio Flusso adapts to a new system. There's a good chance he doesn't understand the current system he's in, if we're being honest. Now as a two-way d-man, you'd ideally want this player understanding the ins and outs of a coaching staff's design for the team's play on the ice. But here we are. Just hits the ice, plays his game in a nice simple way, goes home and cashes his paycheck. Adjusting to the team itself is pretty simple as he's a player who keeps to himself and says as little as humanly possible. The new team, in a perfect world, will never even notice they acquired a new player at all. He might make an introduction at first, but after that, hopefully a season will go by without him having to do or say anything. He will play his game as perfectly as possible so the coaching staff never has to go over anything with him and his team, so that he can avoid any professional interaction with his teammates as well. He'd just show up, do his job and never bother anyone. So, business as usual.
